Bioactive Compounds Studies On The Flowers Of Tagetes Erecta L.

Tagetes erecta.L is a Compositeae family plant. It is used to as flavoring agent, and it is often used in sedation, depressurization, broaden bronchus, heat-clearing and detoxicating, dissipating phlegm and stopping coughing, spasmolysis, anti-inflammatory etc.. Tagetes erecta L. is widely used in clinical application, such as upper respiratory tract infection, whooping cough, conjunctivitis, oral cavity inflammation, odontalgia, pharyngitis, vertigo, children infantile convulsion, amenorrhea, blood stasis, stomachache, ulcerative carbuncle, rheumatism and so on.Two new compounds named 3-α-galactosyl disyringic acid 15-a, 3-β-galact-osyl disyringic acid 15-b, have been isolated from the flower of Tageteserecta.L, they are optical isomer mixture. Their structures were elucidated on the basis of spectral data. In addition, 22 other compounds have also been isolated and 20 of them were identified as tetratriacontane 1, dammarenediol II 3-o-n-palmitate 2,β-amyrin 3, 16Z,19Z-pentacosadienoic acid 4, uvaol 5,β-sitosterol 6, stigmasterol 7, Vitamin Eα8, 9Z,12Z,15Z-octadecatrien-l-ol 9, monolinoleoyl glycerol 10, syringic acid 11, 3,4-dihydroxybenzonic acid 12, quercetagetin 7-methyl ether 13, quercetagetin 14, n-hexadecane 16, quercetagetin 5-methyl ether 17, 5,7-dimetho-xy quercetin 18, gallic gcid 19, 3,4-dihydroxy-5-methoxybenzoic acid 20 and quercetagetin3-o-glucoside 21. Compounds 2, 3, 4, 5, 8, 9, 12, 19 and 20 were isolated from the plant for the first time.
